Problems with central heating

[Pagie1980]

Firstly. They're two different types of manufacturers.
If replacing would be easier to get the same as they don't operate the same direction to open / closed,once installed and wired with colours and locations.

Thanks. I don't believe you can still get the switch mater anymore.

Are you sure the valve has been fitted the correct way round?
It should be "a" to radiators and "b" to hot water.

Yes as far as I know upto the hot water and down to the heating

If boiler keeps running it must be getting a power supply from something, need to rewire system, difficult to make out what it is without being on site think you will find it was the switch master that had 6 wires , Honeywell has 5.

Thanks. Yes seems to be the case. If the boiler is connected to a permanent live though should the thermostats not still shut it off ? Sorry you may be right re the wiring. To be honest I'm absolutely a waste of space with any sort of diy ! Thanks everyone for your help on this matter.

As Massod has suggested, download the wiring guide and get him to completely rewire it
Should only take him 20 mins
You could download the conversion diagram, but I suspect he wont remember where the original wires went, so best to do as above

Problem is electrical. If you don't have 10 point wiring centre, go buy one, download Honeywell guide as Masood has said and wire accordingly. It is possible that contact points on cylinder stat. have fused together, if so this is easily determined once wiring is displayed in an orderly manner.
